"UNTTE STAE PATENT ANDREW PHILLIPS, OF CONElVIAUGI-I, PENNSYLVANIA.

V REVERSIBLE ROTARY STEAM-ENGINE.

Application filed April 26,

To all whom it may concern.-

Be it known that I, ANDREW PHILLIPS, a British subject, residing at Conemaugh, in the county of Cambria and State of Pennsylvania, have invented certain new and useful Improvements in Reversible Rotary Steam-Engines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it ap pertains to make and use the same.

This invention relates to steam engines, and more particularly to an engine of the reversible rotary type.

object of the invention is to provide a rotary motor or engine having a novel arrangement ofsteam feed pipes, a valve for controlling the flow of steam through the pipes whereby the direction of rotation of the rotor may be quickl I and easily reversed, and to provide a rotor which includes a plurality of spaced sections.

other object of this invention is to provide a rotary steam engine as specified which embodies a novel type of rotor including a plurality of spaced rotors having radiating blades attached thereto, and to mount stationary blades intermediate the rotors, for deflecting the steam from one rotor to the one next thereto and also to position the stationary blades, so that one half of the blades will deflect the steam in one direction and the other half in another direction, for regulating the rotation of the rotors upon the inlet of the steam.

With the foregoing and other objects in view this invention consists in such novel features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawings and claimed.

In describing the invention in detail reference will be had to the accompanying drawings wherein like characters designate iie and corresponding parts throughout the several views, and in which:

Figure l is a side elevation of the im proved rotary engine.

Fig. 2 is a fragmentary section through the engine.

Fig. 3 is a detail perspective of one of the rotor carried blades.

the rotary engine illustrating the manner of attaching the blades to the rotors.

Referring more particularly to the drawings, l designates the casing of the rotary engine, as an entirety, through which a shaft 2 extends. The shaft 2 is rotatably sup ported by suitable bearings 3, which bearings are in turn supported by a bed plate or block l. A coupling 5 is mounted upon the shaft 2 for transmitting the power generated by the rotation of the shaft to any suitable piece of machinery.

The casing 1 has a partition 6 mounted therein, which coaets with one end of the casing for forming a steam chest 7. Steam is let into the steam chest 7 through pipes 8 and 9, and its passage is controlled by a three-way valve structure 10. The steam passes through the pipe 11 into the threeway valve structure 10, and by adjusting this valve, it may be permitted to flow through eitherthe pipe 8-into the steam chest or the pipe 9 into the steam chest as desired, depending upon which direction it is desired to have the shaft 2 rotated.

The cylinder or casing 1 has a plurality of rotors 12 positioned therein which are mounted upon the shaft 2, in spaced relation to each other as clearly shown in F 2 of the drawings.

The rotors 12 have blades 13 attached to their, peripheries in any suitable manner as shown at 14, which blades are provided with concaved faces as indicated at 15.

A. plurality of stationary blades Illi are attached to the innerwall of the cylinder 1 and in spaced relation, about the circumference of the same, and they are provided for deflecting the steam from a horizontal. into an angled path with respect to the shaft 2, from one of the rotors to the rotor next thereto. The stationary blades 16 have concaved faces as shown at 17, and the blades in one-half of the casing or which are positioned upon one side of the shaft 2 are curved in one direction, and the blades upon the opposite side are curved in the opposite direction, as clearly shown in Fig. 2 of the drawings.

Nozzles 18 extend through the wall or partition 16 and they are arranged for guiding the steam so that it will strike the blades 13 of the first of the rotors at an angle, for rotating the rotors. The nozzles 18, are positioned in the upper portion of the partition so that the steam passing into the steam chest through the pipe 8 will be guided thereby into the interior of the cylinder and against the blades 13 which are carried by the rotors 12 for rotating the rotors and consequently the shaft 2 in one direction. lhe nozzles 18 extend diagonally through the lower" portion of the partition 6, so that'the steam entering the chamber through the pipe 9 will be deflected by these nozzles agamstthe blades 18 for rotating the rotors in the direction opposite to that which they are rotated by the steam passing through the nozzles 18.

During the operation of the rotors, the steam will leave the blades of one'rotor in substantially ahorizontal plane, and the stationary blades 16 will engage the steam and change its path so that it will strike the blades upon the rotor next thereto in the same manner inlwhich the steam strikes the blades upon its passage through the nozzles 18 or 18, thereby rotating all of'the rotors in the same direction and preventing a connterraction of the steam upon the variousrotor blades. I v y V In reducing the invention to practice, certainminor features of construction, co1nbination and a rrange1 1 1 ent of parts may necessitate alterations to which the patentee is en- Oopies of this patent may be obtained for five cents each, by addressing the Washington, 110.

titled provided such alterations are comprehended witl'iin'the scope of what is claimed.

lVhat is claimed is A reversible steam engine comprising a casing, a shaft jonrnaled in said casing, a partition located in said casing to form a pair of steam chests, means for admitting steam within either of the chests,

a-plurality of relatively spaced rotors secured to the shaft, blades attached to the peripheries of the rotors and having concave faces, a plurality of stationary blades having concave faces secured to the wall ofthe casing between the rotors for deflecting steam from a horizontal path into an angled 'path with respect to the shaft from one rotor to the adjacent rotor, said stationary blades in one half of the casing being curved in one direction, while the stationary'blades of the other half of the casing being curved in the opposite direction, and nozzles carried by the partition for V lirectingsteam on the retors from either chest to drive the rotors in either direction. 7 p p In testimony whereof I allix my signature in presence of two witnesses.
